Universal Law of Gravitation
The universal law of gravitation states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
The gravitational force between two objects is given by the equation:
F = Gm1m 2/r 2
where:
- F is the gravitational force in newtons
- G is the gravitational constant, which is 6.674 × 10 -11N m 2/kg 2
- m 1and m 2are the masses of the two objects in kilograms
- r is the distance between the centers of the two objects in meters
Worksheet Answers
| Mass (kg) | Distance (m) | Gravitational Force (N) |
|---|---|---|
| 1 | 1 | 6.674 × 10-11 |
| 2 | 2 | 2.669 × 10-11 |
| 3 | 3 | 1.471 × 10-11 |
To solve the worksheet problems, we use the equation F = Gm 1m 2/r 2.
For example, to calculate the gravitational force between two objects with masses of 1 kg and 2 kg, and a distance of 1 m between them, we would use the following equation:
F = (6.674 × 10-11N m 2/kg 2) × (1 kg) × (2 kg) / (1 m) 2= 6.674 × 10 -11N
Applications of Universal Law of Gravitation: Universal Law Of Gravitation Worksheet Answers
The universal law of gravitation has many applications in astronomy.
- It is used to calculate the motion of planets and other celestial bodies.
- It is used to design spacecraft trajectories.
- It is used to study the structure of galaxies.
For example, the universal law of gravitation can be used to calculate the speed of a planet in orbit around the sun.
The speed of a planet in orbit is given by the equation:
v = √(Gms/r)
where:
- v is the speed of the planet in meters per second
- G is the gravitational constant
- m sis the mass of the sun in kilograms
- r is the distance between the planet and the sun in meters
Limitations of Universal Law of Gravitation
The universal law of gravitation does not account for certain phenomena, such as the bending of light around massive objects.
The bending of light around massive objects is due to the curvature of spacetime.
The curvature of spacetime is caused by the presence of mass and energy.
The universal law of gravitation does not take into account the curvature of spacetime.
Therefore, the universal law of gravitation is not applicable in situations where the curvature of spacetime is significant.
